I really think it makes a difference where they are placed for sound quality and where the secondaries go is kinda a perfect place.

I was an idiot and did the Akropovic setup downpipes back which was a WAIST of money IMHO.. Dont get me wrong, it does sound good but not for the money I paid. I can do exactly what you did or my buddy actually and get similar results without the money I spent :-/

Oh well lesson learned
I saw your post a while back and you literally save me $2800 lol! So do the regular vibrant resonators still perform close to the "quite" ones? Do they obstruct flow at all our is us just more packing.
